Who cares? It's Poland. Their government hates Europe and dreams about reaching a level where they can compete with all those evil other countries' industries (the sole reason to buy Korean tanks is that those promised some tech transfers). They will of course only buy from the US and happily so... also in completely rediculous numbers they can't actually afford, because like any shitty right-wing government running purely on their own superiority and blaming other countries, it's important to have a strong military.
